Xiaomeng Huang updated HIVE-7730:
---------------------------------
Description:
-Now what we get from HiveSemanticAnalyzerHookContextImpl is limited. If we
have hook of HiveSemanticAnalyzerHook, we may want to get more things from
hookContext. (e.g. the needed colums from query).-
-So we should get instance of HiveSemanticAnalyzerHookContext from
configuration, extends HiveSemanticAnalyzerHookContext with a new
implementation, overide the HiveSemanticAnalyzerHookContext.update() and put
what you want to the class.-
